Detroit made it 6-0 in the sixth when Ronny Rodriguez hit an RBI double and scored on Iglesias's single over a drawn-in infield. A throwing error by left fielder Phillip Ervin allowed in another run.

Cincinnati also threw away two relay throws to the plate, both allowing runners to advance on the bases.

"That was just bad baseball," Reds interim manager Jim Riggleman said. "It is great effort, but bad performance. We have to find a way to clean that up."

Cincinnati closed to 6-4 in a four-run seventh, starting the inning with six consecutive hits off Alex Wilson that included Preston Tucker's RBI single and Curt Casali's two-run double.

Billy Hamilton added an RBI single off Louis Coleman, but Casali was thrown out at the plate by Rodriguez from first when he tried to score on a groundout.

"It was just not a good baserunning play on my part," Casali said. "The hesitation cost me. I wish I could go back, because that was a rally-killer on my part."

Rodriguez, who replaced Adduci in the sixth, finished with two hits and two runs. Adduci also had two hits, including the homer.

"That's great strategy, I guess," Gardenhire said. "They went to the lefty, and Rodriguez was the obvious move, but he made me look good."

JaCoby Jones, who forced Joey Votto at second on an apparent bloop single in the top of the eighth, had an RBI single in the bottom of the inning.

"I put my hand up like I was going to catch it, and that froze him," said Jones, a converted shortstop. "After that, I was just playing it like an infielder and trying to make a good throw."

TRAINER'S ROOM

Reds: With OF Scott Schebler (right shoulder) still waiting to start a rehab assignment and OF Jesse Winkler having season-ending shoulder surgery on Tuesday, Tucker was Cincinnati's designated hitter and will see action in the outfield.

Tigers: LHP Francisco Liriano is scheduled to start Sunday in Oakland. The allergic reaction that caused him to miss his first start after the All-Star break was finally determined to be caused by a chemical used on his lawn in Miami.
